Design

The Veyron’s bold proportions, well-balanced surfaces, and clear line structures give an impression of pure, sleek elegance.

The design of the Veyron honours a great heritage without drifting into retro style. Every detail of the classic two-tone colour scheme, a nod to the 1920s and 1930s, has been carefully thought out, resulting in the typical Bugatti profile with the classic, contrasting ellipsis - the stylistic element used by Ettore Bugatti himself.

The “crest line”, which runs uninterrupted from the hood to the only 1.21-m-high roof, is a proud homage to the Veyron’s forebears. Thus, the Veyron’s classic paintwork and harmonious design connect this state-of-the-art super sports car to the glorious heritage of Bugatti automobiles.

With its classic look, the large radiator grill - adorned with the hand-enamelled Bugatti emblem - represents the grandness of the Veyron. The sports car’s distinctive front is defined by the harmonious contrast of its broad headlights and majestic grill. The rear end, features the formidable retractable spoiler and generously designed bumpers.

The Veyron perfectly fulfils the main design objective governing the development of the new Bugatti: an uncompromising combination of highest elegance and state-of-the-art technology.

Interior

Every aspect of the Veyron 16.4’s interior focuses on essentials.

Clear lines dominate the design, and all controls reflect a meticulous attention to detail - the selection and finish of the prevailing materials aluminium and leather meet the highest possible standards. A unique alloy was specially developed to guarantee the consistent aluminium shine. Only the choicest leather - free of even the tiniest blemishes - was used for the interior. The light-alloy steering wheel is a work of art, a composition of aluminium spokes, a leather cover, and convenient rocker switches offering easy access to the car’s sports automatics functions. The satin-aluminium finish of the handcrafted centre console rounds off the elegantly sophisticated look.

Designers and engineers worked closely together to integrate every single one of the Veyron’s many features - from GPS to seat heating - harmoniously in the cockpit, without allowing it to appear excessive or too complex. The unique sound experience provided by the integrated sound system was designed by the high-end specialists at Burmester in Berlin. The Veyron is the first car to boast Burmester system elements that were originally developed for home use. Each component was specially adapted for the Veyron to meet Bugatti’s extremely high quality standards.

It is these precious details that distinguish the Veyron, creating a unique Bugatti atmosphere. Yet the true perfection of a sports car that exceeds all expectations results from the harmonious combination of these details - a balance of emotion, reflected by the bold design, and superior craftsmanship.

Technology

With its 16-cylinder four-wheel drive, the Bugatti Veyron 16.4 may well be the most sophisticated production vehicle of all times.

Boasting a maximum speed of more than 400 km per hour, the Veyron is unmatched in the super sports category. It offers a total of 1,001 HP, and its ample power reserves even at high speeds are the fabric of dreams for luxury-class limousines: for a constant speed of 250 km/h, the Veyron only needs 270-280 HP.

The Electronic Stability Program (ESP) ensures the necessary flexibility and manoeuvrability at any speed. The Veyron reaches velocities that would literally lift the car off the ground - if it weren’t for its ingenious aerodynamics, which keeps it firmly on the road even at full speed. Adjusting the back spoiler, reducing ground clearance, opening and closing the lids - it all adds to the perfect balance between propulsion and downforce. Such a super sports car may not seem to be brought to a halt easily, but the Veyron’s ceramic brakes slow it down faster than it can accelerate. While it takes this exceptional car only 2.5 seconds to go from 0 to 100 km/h, it needs even less time - a mere 2.3 seconds - to come to a standstill from 100. All of these technical details combine to make the Veyron a truly exceptional super sports car.

Acceleration

The Veyron uses the same launch control technology as Formula 1 racing cars to ensure maximum traction from first to seventh gear and up to the 400 km/h maximum speed.

The electronically controlled acceleration takes the car from standstill position beyond the 400 km/h threshold in less than one minute. Just activate launch control, engage gear, control the steering wheel, place your left foot on the brake, and keep your right foot on full throttle. If you release the brakes swiftly, you will accelerate on a par with veritable Formula 1 cars.

The mighty, 1,001-horsepower sixteen-cylinder four-wheel drive can be felt and driven through a widerange of engine speeds. A constant 250 km/h requires only 270-280 of the Veyron’s horsepower meaning that more than 700 HP are continuously “on standby” for quick and fast interludes. With this kind of power and pull, the Veyron manages racecourses as easily and competently as lonely mountain passes or rushhour traffic in Tokyo.

Speed

The Veyron 16.4 is the fastest production vehicle of all time.

For years, the Bugatti engineers worked diligently in order to push the 400 km/h boundary. No wind tunnel can simulate this velocity, which is why after each of a long series of improvements, the different ground clearance levels and the modifications of the rear bumpers, spoiler and underbody were tested separately on high-speed test ranges. This ambition and persistence paid off, as the official speed measurement proves.

The Veyron’s high velocity is due to the perfect combination of engine technology, consistent lightweight construction, specially developed tires, and the complex balance of propulsion and downforce.  Not only aerodynamic drag plays a crucial factor at very high speeds, but also the precise adjustment of the downforce that holds the car to the road surface. In addition to this raw speed, the Veyron also meets the highest safety, reliability and maneuverability standards requires by even the most discerning drivers.

To create the optimum aerodynamics, the Bugatti engineers developed three configuration modes.

Standard mode - used for speeds up to 220 km/h, the rear spoiler system is completely retracted. In handling mode, used at higher velocities, the vehicles nose is pulled down and the monumental rear spoiler deployed. This produces an additional 350 kg of downforce without compromising the Veyron’s exceptional handling.

Top speed mode - for velocities beyond 375 km/h, which is activated before the engine is started. In top speed mode the front diffuser flaps are shut to make the underbody absolutely level, and the spoiler is lowered and completely aligned with the chassis, forming a tearing edge - thus, the Veyron is perfectly adapted for top velocities. The downforce is reduced to minimize the strain on the tyres. The car is held down on the road by its own weight and the downforce. The Veyron starts immediately at top speed mode, allowing only for a limited turn of the steering wheel. As soon as the driver brakes, the Veyron automatically switches to handling mode. But those who dare to accelerate consistently on a long, straight road will experience the power of the fastest production vehicle of all times

Handling

The Bugatti’s Veyron 16.4 is the first super sports car with guaranteed ESP functionality at all speeds including top velocity, tested and approved by exceptional race car drivers.

The first ESP tests at velocities beyond 300 km/h were performed on the dried salt lakes in the American Southwest where the low-friction ground surface is ideal for taking a car’s road grip to the limit. Featuring intelligent four-wheel drive and four electronic controls, the Veyron is as safe as it is fast. Two steerage systems, a Haldex clutch, and the rear axle locking differential provide the necessary dynamics, while the brake pressure regulation and active torque control ensure controllability.

In addition to the ingenious electronic controls, the Veyron 16.4 features high-precision engineering and a perfect underbody based on state-of-the-art racing technology. Double traverse control arms in the front and rear guarantee precise wheel control. All elements work smoothly together with minimal friction and a maximum of stability. Suspension, cushioning, and stabilizers react directly and immediately.

The steering system is equally well balanced: the high connection stiffness of all elements ensures direct reactivity. The car follows each and every move of the driver, at any speed and with exactly the right dose of servo support. The latter is gradually decreased towards top velocity, making for easy manoeuvrability in city traffic without compromising smooth directional stability at high speeds, and precise, flawless corner turns on country roads.

The tires are the last, but certainly not the least factor determining driving dynamics and security. The Veyron 16.4 tires feature a specially developed rubber compound, customized tire tread, and an elaborate tire pressure control system.

Braking

There is one thing the Veyron 16.4 does even faster than accelerating: braking.

The Bugatti Veyron exploits the full range of available technologies to allow for ultra-fast deceleration. It takes less than 5 seconds to get from 0 to 100 km and back to a complete standstill. In theory, that is, for such a feat would require the driver to react with nearly superhuman speed. The whole braking process takes no more than 31.4 meters or 2.3 seconds - that is less than the car needs to get from 0 to 100 km. And even the 400-to-0-km/h deceleration is a matter of less than 10 seconds.

Made of high-tech carbon, ceramic, and titanium materials, the brake system guarantees consistently high friction values and optimum cooling. Intelligent carbon-ceramic brake discs with interior ventilation, eight-piston monoblock caliper units in the front, and six-piston caliper units in the rear ensure the necessary driving agility on a par with professional racecars.

The rear spoiler serves as an additional air brake at speeds beyond 200 km/h. Activated by the brake pedal, the spoiler shoots up and is deployed at a 55-degree angle in less than 0.4 seconds. Tests including repeated follow-up brake maneuvers have shown this brake system to be not only the most powerful, but also the most reliable and durable ever built into a serial production vehicle. It boasts deceleration values of up to 1.3 g, with an additional 0.6 g support by the rear spoiler. Even during full braking maneuvers at top velocities, these brakes won’t give. Brake fade, the much feared performance reduction after repeated application of the brakes - e.g. during long downhill drives - is virtually impossible.

Lightweight Construction:

A super sports car like the Veyron 16.4 needs to be light in order to reach top speeds.

From the initial concept to the design and the selection of materials, the Bugatti engineers tapped the full potential of their considerable expertise to ensure that this car is, indeed, a lightweight. Titanium, carbon, magnesium, and aluminum - each part of the Veyron 16.4 is made of the material with the lowest weight and the highest level of functionality - The titanium piston rods save approx. 4 kg of weight, the titanium screws 3.5 kg, and the magnesium valve caps another 2 kg.

By reducing the wheelbase, the original weight was reduced by about a third, and the titanium exhaust system - another Veyron 16.4 first - with its wafer-thin layer of titanium aluminite saves yet another 17 kg. These combined efforts capped the Veyron 16.4’s weight at a compact 1,888 kg. Add the car’s high-powered performance and unmatched speed, and you have a uniquely fast and nimble super sports car.

Optimum protection is guaranteed by the car’s carbon monocoque construction: weighing only 110 kg, the survival cell withstands enormous crash impact forces. This principle is comparable to that used in the Formula 1 world, where drivers usually emerge uninjured from their cars even after severe accidents. The maximum impact force reduction is mainly due to the frames integrated in the carbon monocoque. The front part of the monocoque is made of aluminium; the rear consists of a combination of carbon, stainless steel, and aluminium. The car’s safety concept, which includes two frontal airbags for the front-seat occupants, is so sophisticated that additional airbags would be redundant. Crash tests have shown the Veyron 16.4 to conform to all international safety standards - and to exceed them. As painful as it was for the engineers to watch their valuable prototypes hit the test wall, they were always glad to see that the Veyron survived these manoeuvres almost unharmed.

One for the driveline, one for the convenience functions, and one for the internal diagnostics system. A total of 26 control devices are connected to these buses. This digital network comprises the car’s complete intelligence system: from engine regulation to electric windows; from rear spoiler control to GPS. In place of a traditional network, Bugatti equipped the Veyron with a lightweight onboard network also used in aviation technology. This saves 5 kg of weight and also offers extreme temperature resistance.

The hub of this network is the telemetry computer. It constantly collects all vehicle data, checks them for reliability, and monitors battery voltage. As soon as the values become critical, the computer automatically transmits an error report to Bugatti - from anywhere in the world. Whenever there’s the possibility of a malfunction, there is also perfect service available. Customers may of course deactivate this option, but they can also intensify the service level: the Veyron’s GPS data are always accessible in case the car should go missing.

In addition, the Veyron features speech-controlled, hands-free mobile phone operation with integrated Bluetooth technology. The Bluetooth GPS is controlled via an exclusive Bugatti PDA. Both systems use the Burmerster sound system for crystal-clear audio output. All visual data are displayed on the rearview mirror - a feat made possible by the extremely bright LED display placed behind the semi-transparent mirror glass. The PDA boasts additional useful features: drivers can use it to access lap times, tire pressure, gas consumption, and key telemetry data.
